TYPEWRITING .IJACHINE.

Application filed September This invention relates to means for positionlng and.holdm cards on a tvaewrit-er p t: v platen to receive typing. I

In certain kinds of worl: as for example. 7 7 L trei'ne'hottoni of the cards.

One of the pr ncipalolnects of the present'invention isto provide in'iproved means for the purpose specified, simple in struc i ture, economical tomanufacture, effective in use and readily applicable to standardanafor the side edges oi thecardas it is thrust. down, and also having fill-HS ends fingers which extend downwardly tromthe table.

.andareprovided immediately below the printing line svith individual gages which co-operate. to arrest the card in a-single printing position ileaving the bottom edge oi? the card entirely exposed to the types; the whole device-being permanently mounted upon the platen-frame and therefore dissimilar to the class of stencil-card-feeders, .in'which the stencil-card is fed line by line at the typing operation, and in which itis impossible to'writeupon the bottoinnedge of the card.

i In carryingoutone form of the invention, provision is made of a cross :mcmber or strip attached at its ends to the ends of the platen-frame, and so arranged as to support a card-holder in substantially vertical position at the-delivery side of the platen. The cardsholder comprises table, preferably formed of two separate sections oralignen plates adju'stably secured to the bar to enable the width of the table to be varied according to the widths of the cards to be used. At the side edges of the table there .are side gages perpendicular to the table, and resilient members or plates extend from the tops of the side gages inwardly over the .table to form chutes to receive the. side edges of the cards and to press the cards against the table to detain them against accidental displacement. The resilient members are bent-towards the table so as to press the cards against the table and are flared ont- 11,1923. 7 Serial No. 662,639.

.weirdly diagonally across their upper and inner edges, to facilitatetheinsertion otthe sideed es oi the card between the resilient members in special filing systeins suehas ltllB Card-n e21 system, it is necessary to type on the e:-:-.

and the table which-is providedat each side with a linger-- extending-down; wardly acrnss the printing linegand having -i outwardiy-projecting lower end .to P tlzehotttnn edge of the card. The sidesstantially to the printingt-line and :the re t memhers,. whichgradnall' decrease inwidth, are continued downwardly to the same extent. as the side-gages.

According to a second form of 'theinven- .tion, the iinge's extending downwardly from the table in thefirst form and also the" corresponding portions not the side gages are omitted, and the ;downwardlyextending portions orfingers of the resilientmembers are'continued across the printing line and turned toward the platen at theirlower ends to tormg-ages tor thebottom edges of the cards. r i

According to a third tormsof t-heinvention, the chutes at the sides ofxthetable are extended across the'printingline, and, are

providedwith closed lower ends-to provide gages for the bottom-edges ct the-cards.

Other features and advantages will hereinatt-er' appear.

means of type-bars 17 having types 18 there- -.on.

In case. the machine is in ,useaafor typing single lines on a plurality of cards inserted in succession, the feed-rolls 15 and 16 are usually castoff and special means provided for holding. the inserted cards in position to receive typing.

In carrying out the invention, provision is made of a strip or bar 19 having rearwardly offset lugs 20 resting on the ends 13 of the platen-frame and bridging said ends and secured thereto by means of thumb screws 21, the main portion of the bar or strip 19 being substantially vertical. Adjustably mountedpn the bar are aligner plates 22 which constitute a table 23 substantially tangential to the platen at the delivery side thereof. For securing the aligner-plates 22 to the bar 19, provision is made of vertical slots 24 in the'bar and of horizontal slots 25 in depressed portions 26 of the aligner-plates, which are held in position on the bar'by means: of screws 27 ex tending through slots 25 in the plates and certain slots 24 in the bar-and threaded into strips 28 at the rear of the bar. It should be noted that, as a result of providing the horizontal slots 25 in the depressed portions of the aligne-r-plates, the heads of the screws lie to the rear of the surface of the alignerplates. Asdisclosed in Figures 1, 2 and 3, the tables are arranged for use with comparatively narrow cards 29. If wider cards are to be used, however, the aligner-plates may be adjusted farther apart, if necessary, by utilizing the unused vertical slots 24 shown at the right and left of the tables in Figures 1, 2 and 3.

In the form of the invention shown in Figure 1, the alignenplates are provided with narrow extensions or fingers 30 extending across the printing line, and having at their lower ends outwardly-projecting portions 31 to serve as gages for the bottom edges of the cards. At their outer edges the aligner-plates are provided with side gages 32 perpendicular thereto, which may be either integral therewith or secured thereto by suitable means, as by soldering or brazing. From the upper edges of the side gages 32 resilient members or plates 33 extend in wardly over the aligner-plates and are bent toward the aligner-plates, as shown in Figures 4, 5 and 6, to press against a card positioned thereon'to hold the same in posi tion, and are flared away from the alignerplates diagonally across their upper and inner edges to facilitate the insertion of cards from above. In this form of the invention the side gages 32 and the fingers 34 or narrow extensions of the. resilient members are continued substantially to the printing line. Notwithstanding this hugging of the worktable 23 by each of the wings33, it is still easyto insert a card, each wing or clip at its inner position being bent obliquely forward and sidewise, or on a bias, the diagonal axis ofthe bend being indicated at 33*, Figure 1. The'lower corner of the card may be inserted in the throat formed by the co-operation of the work-table with the diagonally bent or flaring wing, and may be used to wedge this resilient wing or clip forwardly to permit the card to be pushed behind the bodyportion of the wing and to be clipped thereby to, the work-table 23. Either wing maybe used in this manner, and the card the then readily slips into place between other wing and the work-table.

According to the second form of the invention, Figure 2, the narrow extensions or fingers 34, at the front of the cards, are

continued across the printing line and bent rearwardly to form gages 35 for the bottom edges of the cards, the downward extensions 30 of the aligner-plates and the corresponding portions of the side gages 32 being omitted. In "this form of the invention the card 'is held more closely against the platen since the fingers 3O projecting downwardly from the aligner-plates are omitted. According to the third form of the invention, Figures 3 and 6, the chutes 36 formed by the extensions of the aligner-plates, the

side gages, and the resilient members are extended across the printing hue and are entirely closed at the bottom, forming pockets,

the inwardly-bent flanges 37 of which serve to gage the bottom edges of the cards. In Figure 4 the flange 31 is shown as bent 'forward to form a bottom gage. In Figure 6 the combination with a platen and a platen-' frame, of a pair of card-holding chutes open at the top and permanently fixed to the platen-frameand arranged above the printing line and receiving both side edges of a card as it is thrust downwardly at the front of the platen toward the printing line thereon, said chutes having guides above said printing line for the side edges of the card and also having both front and back relatively broad members above the printing line for supporting and guiding the card, said broad chutes merging into relatively narrow downward extensions at the side edges of the card crossing the printing line and leaving the bottom edge of the card ex posed substantially for its entire length and terminating immediately below the printing line, and said extensions having means engaging the bottom edge of the card to locate the card with its bottom edge portion exposed to the types at the printing line.
